How do we create more transparency and promote more trust in the digital supply chain? The digital advertising industry has grown exponentially, and with that has come issues of fraud, transparency and the trust problems inherent in such growth. The IAB Tech Lab in the USA is the tip of the spear in dealing with these issues by developing tech solutions and industry standards, and in this episode we talk to Dennis Buchheim, Senior Vice President & GM of IAB Tech Lab, about the current and recent Tech Lab projects that aim to deal with these issues to the benefit of the whole industry.
